- IMPROVEMENT 1N GlGGING-iMAGHl-NES FOR NA'PPING CLOTH.

Specification forming part of Letters Patent No. 260 784, dated February26, 1878; application filed September 22, 1877.

To all whom 'it maybe-mam Be it known that we, CHRISTIAN WGELFEL andJAMES MASSEY, of Chester, in the county of Delaware and State ofPennsylvania, have invented a new and l mproved Gigging-Machine forNapping Cloth, of which the following is a specification: K

In the accompanying drawings, Figure 1 represents asectional sideelevation of our improved gigging-machine Fig.2,. a. .plan View of thesame, partly in horizontal section, on line w w, Fig.1; Fig. 3 is adetail side view of the adjustable bracket-plate, supporting-guiderollers and napping-cards; and Fig. 4, a detail side view of themechanism for movin g the cloth-conducting table or apron.

Similar letters of reference indicate corresponding parts. l Thisinvention relates to improvements in the gigging-machines for whichLetters Patent have been granted heretofore to Carl Gerber, Sn, andChristian Woelfel, dated February 1, 1876, and numbered 172,991, so thatthe cloth is dressed ina superior manner, the nappingcards adjusted tothe cloth during the passage of the same through the machine, and thecloth taken up at the lower part of the machine and carried from oneside to the other without dragging the cloth or throwing the powerrequired to move it on the takingup and stretching rollers.

The invention consists of the combination of guide-rolls andreciprocating napping-cards with adjustable bracket-plates of the mainframe, said bracket-plates being guided in recesses of the frame, andset by suitable screwgear, while the napping-cards-are reciprocated atright angles, or at any other lateral angle of inclination, to the clothby means of eccentrics and vertical shafts.

At the lower part of the machine is an endless movable table or apron,that is slowly moved by suitable gear-connection with thestretching-rolls, to carry the cloth from one side of the machine to theother.

Referring to the drawings, A represents the supporting-frame of ourimproved giggingmachine, the frame being of rectangular shape, and of asize corresponding to the number of wire cards B employed. The wirecards E;

or all the sides, and are attached by clamping-sc-rews, or otherwise, tothe ends of sliderods 0, which are guided in sleeves a of detachablebracket-plates D, that are supported in an adjustable manner on theuprights of frame A.

., The cards are arranged between pairs of guide-rolls E, that turn inbearings of the bracket-plate D, the cloth being passed between theguide rolls, and-moved through the machine to be exposed to the actionof the cards by taking-up and stretching rolls E E The napping cards arereciprocated in planes at right angles to the cloth by means of twoupright shafts, F, having a number of eccentrics, b, on each shaft, theeccentrics being connected by encircling straps d and arms at with theslide-rods G, and so arranged on the shafts that they will work all thecards at the same time, but one after the other.

The slide-rods C may also be arranged at a suitable lateral angle ofinclination to the bracketplates D, whose sleeves are then cast orotherwise arranged at a corresponding angle, so that the cards strikethe cloth at a plane at aright angle thereto, but at a lateral angle toeither side, by which the bottom of the warp may be reached, and the napraised much better than when all the wire cards strike the cloth atright angles. This angular motion of the cards to the cloth is clearlyshown in Fig. 2.

The upright shafts and eccentrics impart to the cards a steadier motion,without jar or loss of motion, and cause them to strike the cloth moreevenly. The mechanism is more durable, capable of being run at greaterspeed, and not as liable to get out of order as the crank and levermechanism heretofore employed.

The bracket-plates D are guided by side rails e on horizontal dovetailguides e of frame A. and made adjustable therein by suitable gearing andscrews, as shown in Figs. 1 and 3, so as to move the bracket-platesforward or back, and bring the guide-rolls and the cloth closer to, orfarther away from, the napping cards.'

may be regulated while the machine is in motion, saving thereby muchtime, for when the are of squareshape, with wire clothing on one wirecards are once set on the slide-pieces The degree of striking-force ofthe cards they remain set thereon, and need not be moved or taken ofl,as the striking of the cards on the cloth is regulated by adjusting thebracket-plates with the screws and gear. It is therefore not necessaryto take off the wire cards either to put the cloth on the machine orwhile the nap is being laid on by the napping-rollers G at the top ofthe machine, the striking of the cloth being quickly regulated for allgrades of cloth while the machine is in motion.

Atthe lowerpart of the machine is an endless apron or table,H,which isslowly moved by gearwheel and worm-connection with the stretching-rolls,(shown in Fig. 4,) for the purpose of receiving thecloth and carryin gitfrom one side to the other, to be delivered to the taking-up rolls E.The apron saves the power required by the stretching-rolls for draggingthe cloth forward under the machine, and gives a more even tension tothe cloth. The stretchingrolls E are revolved by suitable gear, belt, orother connection with the driving-shaft, and the tension of the clothregulated by the speed imparted to the stretching-rolls.

The nap may also be raised on both sides at the same time, if desired,by an extension of the guide-sleeves and brackets from the frame of themachine, the cards being arranged at alternate sides of the cloth.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1. In a gigging-machine, the combination,

with the supporting main frame, of horizontally-adjustablebracket-plates, carrying the guide-rolls, guide-sleeves, and thenappingcards, to regulate the striking of the cloth while the machine isin motion, substantially as and for the purpose set forth.

2. The combination of the adjustable bracket-plates, havingguide-sleeves, guiderolls, and the card-carrying slide-rods, with theoperating upright shafts, eccentrics, and connecting straps and arms,substantially as specified.

3. The combination, with taking-up and stretching rolls and guide-rollsalternating with the napping-cards of napping-cards and mechanism,substantially as described, to reciprocate the same in planes at rightangles to the cloth, and also at a suitable lateral angle of inclinationthereto, whereby the bottom of the warp is reached, substantially as andfor the purpose described.

4. The combination, in a gigging-machine, with the taking-up andstretching rolls, reciprocating cards, and guide-rolls, of an endlessmovable table or apron at the lower part of the machine, to carry thecloth from one side to the other, substantially as described.
